ODATA TABLEAU 

OData (Open Data Protocol) is a standardized protocol for building and consuming RESTful APIs. Tableau is a powerful data visualization and business intelligence tool. You can use OData as a data source in Tableau to connect to various data services and perform a visual analysis of the data.

Here’s a general overview of how you can use OData with Tableau:

1. Connecting to OData in Tableau:

• • Open Tableau Desktop.
  • Choose “Connect to Data” and select “OData” from the list of connectors.
  • Enter the URL of the OData service you want to connect to. This URL should point to the OData service’s metadata document (often ending in “$metadata”).
  • Tableau will read the metadata and display a list of tables and entities from the OData service.

1. Selecting Data and Building Visualizations:

• • After connecting to the OData service, you can select the specific tables or entities you want to work with.
  • Drag and drop fields from the selected tables/entities onto the Rows and Columns shelves to create visualizations like charts, graphs, and tables.
  • Use Tableau’s features to customize your visualizations, apply filters, create calculated fields, and perform other data manipulation tasks.

1. Refreshing Data:

• • Tableau lets you establish a live connection or extract data from the OData service. With a live link, data is fetched in real-time, while an extract creates a snapshot of the data that you can work with offline.
  • You can set up a refresh schedule for the extract to keep your data up-to-date.

1. Publishing and Sharing:

• • Once you’ve created your visualizations, you can save your Tableau workbook and publish it to Tableau Server or Tableau Online to share with others.
  • Tableau Server and Tableau Online provide collaboration and sharing capabilities, allowing others to access and interact with your visualizations.
